Introduction to P&ID
Click here for Piping and Instrumentation Diagram main article The flow sheet or flow diagram are often used in context of engineering and design application. Although this terminology is not most accurate to describe P&IDs, it’s sufficient to describe the overall family of a process based diagram to which P&IDs belong. We can divide the process diagram in three type or step: BFD : The Block Flow Diagram PFD : The Process Flow Diagram P&ID : The Process and Instrumentation Diagram BLOCK FLOW DIAGRAM The beauty of a BFD is its ability to outline the complete process on little more than a single sheet. The diagram usually resemble an organized chart, containing mainly text enclosed by boxes, interconnecting lines, the process commodities they transport and flow arrows to indicate flow directions. INFORMATION PROVIDED BY A BFD A good BFD typically contains the following: Individual pieces of equipment or equipment package that are denoted by a single symbo...
